Downloading the newest software will be free for all existing devices, released next Wednesday, September 18.

"Downloading iOS 7 is like getting an all new phone that you already know how to use," Federighi remarked prior to announcing that the new operating system will be available to download for existing devices next Wednesday, Sept. 18.

Apple's newest iOS 7 update will give its new 2013 devices, including the expected iPhone 5s and iPhone 5c, a new look and several new features.

From typography to color schemes, to icon and button placement and shapes, expect a range of visual changes with iOS7.

Safari has been adapted with extra tools for sharing including AirDrop and more advanced and intuitive tab systems.
